Plan documentation needs updating
Plan effectiveness cannot be validated without recent testing reflecting current environment✔️
Test results are too old to be useful
Management commitment is questionable

Correct Answer Logic:

A DRP must be tested regularly and after significant changes. Successful testing three years ago provides no assurance that the plan works with the current infrastructure. Cloud migration and new applications represent material changes that could render the old plan ineffective. Current validity cannot be assumed.

Education QUESTION #6760

Question 10391

In constructing an effective matching exercise, a teacher has 6 premises in column A and 6 responses in column B, with a strict one-to-one matching rule. What key principle of matching exercise construction is being VIOLATED?

Using homogeneous content
Arranging responses in logical order
Providing an unequal number of responses and premises to reduce systematic guessing✔️
Placing shorter items in the response column

Correct Answer Logic:

One of the most important rules for constructing matching exercises is to include more responses than premises (or allow responses to be used more than once) so that the last premise cannot be answered by elimination. A strict one-to-one correspondence with equal numbers allows students to answer the final item through process of elimination, without any content knowledge.

Administration QUESTION #9538

Question 10392

Taylor's shovelling experiment at Midvale Steel produced a result that was counterintuitive for its time. Which concept did this experiment most directly establish as the basis for Scientific Management?

Hawthorne effect — workers perform better when observed
One best way — a scientifically determined optimal method for each task✔️
Unity of command — workers should receive orders from one superior
Scalar chain — authority flows in a clear line from top to bottom

Correct Answer Logic:

Taylor's experiment demonstrated that there is a scientifically discoverable optimal method ('one best way') for performing any task — in this case the ideal shovel load of 21.5 lbs — as opposed to rule-of-thumb practices. This became the foundational claim of Scientific Management.

Nursing QUESTION #9190

Question 10394

A Charge Nurse is conducting a study using systematic random sampling from a population of 400 patients. She selects every $k^{th}$ patient after a random start. If the desired sample size is 50, what is the value of $k$?

4
6
8✔️
10

Correct Answer Logic:

Correct Answer: C — $k = 8$

The formula for the sampling interval in systematic random sampling is:

\[k = \frac{N}{n}\]
Where:

$N$ = population size = 400
$n$ = desired sample size = 50

\[k = \frac{400}{50} = 8\]
The nurse randomly selects a starting point between 1 and 8, then selects every 8th patient thereafter (e.g., patient 5, 13, 21, 29...). This method ensures equal probability of selection and is more practical than simple random sampling for large populations.

Business, Public administration and Policy QUESTION #10496

Question 10395

Woodrow Wilson contended that government agencies would perform their functions more efficiently by:

Adopting business principles of the private sector✔️
Combining administration and politics
Rejecting the business model entirely
Decentralizing administrative authority

Correct Answer Logic:

Woodrow Wilson, in his 1887 essay The Study of Administration, argued for the politics-administration dichotomy — that administration should be separated from politics and run on efficient business-like principles. He believed that importing private sector management techniques into government would make agencies more effective, productive, and accountable.

Physics QUESTION #7062

Question 10396

A plano-convex lens has a diameter of $6 \text{ cm}$ and a thickness at its center of $3 \text{ mm}$. If the speed of light within the lens material is $2 \times 10^8 \text{ m/s}$, calculate the focal length of this lens.

$15 \text{ cm}$
$20 \text{ cm}$
$30 \text{ cm}$✔️
$10 \text{ cm}$

Correct Answer Logic:

1. Calculate Refractive Index ($\mu$):
$\mu = \frac{c}{v} = \frac{3 \times 10^8}{2 \times 10^8} = 1.5$.

2. Determine Radius of Curvature ($R$):
For a lens with radius of aperture $r = 3 \text{ cm}$ and thickness $t = 0.3 \text{ cm}$, the radius of curvature is given by $R \approx \frac{r^2}{2t}$ (for small thickness).
$R = \frac{3^2}{2 \times 0.3} = \frac{9}{0.6} = 15 \text{ cm}$.

3. Lens Maker's Formula:
$\frac{1}{f} = (\mu - 1) \left( \frac{1}{R_1} - \frac{1}{R_2} \right)$. For a plano-convex lens, $R_1 = R$ and $R_2 = \infty$.
$\frac{1}{f} = (1.5 - 1) \left( \frac{1}{15} \right) = 0.5 \times \frac{1}{15} = \frac{1}{30}$.
Thus, $f = 30 \text{ cm}$.

Academic/Professional (Social Sciences) QUESTION #10137

Question 10397

Two societies show identical social cohesion levels, but Society A's cohesion stems from shared kinship and tribal loyalty while Society B's stems from mutual economic dependence. Which pairing best matches Khaldun and Durkheim respectively?

Society A = Durkheim's organic; Society B = Khaldun's Asabiya
Society A = Khaldun's Asabiya; Society B = Durkheim's organic solidarity✔️
Both represent Durkheim's mechanical solidarity
Both represent Khaldun's Asabiya

Correct Answer Logic:

Kinship/tribal loyalty aligns with Khaldun's Asabiya, while economic interdependence aligns with Durkheim's organic solidarity.

Biology Zoology Botany QUESTION #10821

Question 10398

The biologically active hormonal form of vitamin D is:

Calcitriol✔️
Calmodulin
Retinol
Calciferol

Correct Answer Logic:

Calcitriol ($1,25\text{-dihydroxycholecalciferol}$ or $1,25(\text{OH})_2\text{D}_3$) is the biologically active hormonal form of vitamin D. It is produced by two-step hydroxylation: first in the liver (25-hydroxylation → calcidiol) and then in the kidney (1α-hydroxylation → calcitriol). Calcitriol acts on intestine, bone, and kidney to regulate calcium and phosphate homeostasis. Calciferol is the general term for vitamin D₂/D₃; retinol is vitamin A.

Chemistry QUESTION #7518

Question 10399

In a gaseous mixture, the ratio of masses of oxygen to nitrogen is 1 : 4. What is the ratio of the number of molecules of O$_2$ to N$_2$?

1:08
3:16
1:04
7:32✔️

Correct Answer Logic:

Let mass of O$_2 = 1$ g and mass of N$_2 = 4$ g.

Moles of O$_2 = \dfrac{1}{32}$ ; Moles of N$_2 = \dfrac{4}{28} = \dfrac{1}{7}$

Ratio $= \dfrac{1/32}{1/7} = \dfrac{7}{32}$

So the ratio of molecules O$_2$ : N$_2 = \mathbf{7 : 32}$
